Symptoms of Arrhythmia

Sometimes there are no symptoms to warn of an arrhythmia. Other times, the symptoms are very clear and alarming. Symptoms include:

  • Palpitation, or a skipped beat, which feels like an extra heartbeat
  • Fluttering, a feeling of a number of skipped beats in rapid succession
  • Slow heartbeat, which brings about fatigue, dizziness, near fainting, or fainting
  • Rapid heartbeat, which can cause shortness of breath, chest pain, dizziness, near fainting, or fainting
  • Near fainting—known as pre-syncope—where you may experience lightheadedness or dizziness, blurred or tunnel vision, sweating, headache, mental confusion, stomachache, and nausea or vomiting
  • Fainting—known as syncope—that comes on suddenly without warning

If you experience fainting, especially sudden fainting, see your doctor as soon as possible. In some cases, fainting may be the only warning sign of a serious abnormal heart rhythm.
